영문 초록

This study investigated the changes of antioxidant compounds and antioxidant activity of adzuki bean by drainage methods in poorly drained sloping paddy field. The soil moisture contents of under pipe and open ditch drainage on very poorly drained paddy soil were 18.52±4.58 and 19.01±4.25%, and imperfectly drained paddy soil were 14.87±4.82 and 18.64±3.85%, respectively. Moisture, protein, fat and ash contents of adzuki bean with drainage methods were 10.10~11.60, 14.13~21.75, 0.02~0.73 and 2.81~3.45 g/100 g, respectively. The total polyphenol, flavonoid and tannin contents, and radical scavenging activity of adzuki bean showed significant differences by drainage methods. The total polyphenol, flavonoid, and tannin contents by drainage methods were 2.73~4.14 mg GAE/g, 1.07~1.43 mg CE/g, and 1.27~1.84 mg TAE/g, respectively. The DPPH and ABTS radical scavenging activities were 2.84~4.47 and 5.11~6.74 mg TE/g, respectively. The antioxidant compounds and radical scavenging activity of the adzuki bean by drainage methods were frequently affected soil water.
